[PATCH] D62831: [CodeGen][ObjC] Add attribute "arc_retain_agnostic" to ObjC globals that are retain-agnostic

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

Should `objc` be in the attribute somewhere to avoid any future awkwardness?  I don't remember what we've called similar attributes.
